Maybe that guy in panel three didn't tie his shoelaces. You don't know it was because he was distracted by something!
I know I've talked about how the ability to see red is supposedly carried on the X-Chromosome SOMEWHERE online, and that women can generally see more subtle variations of red as a result, but I'm not sure if I've mentioned it in a commentary before. Well, I AM NOW.
In any case, I like to think of genuine differences that could result from transforming, and literally seeing things somewhat differently is certainly one of them.
Of course, one could nitpick how exactly the transformation would work and such whether it REALLY makes sense for Elliot to see more varieties of red when a girl, but it's magical transformation fiction with a quirk thrown in based on a fun fact. Any and all arguments against it are buried under a tidal wave of "because magic".
